Description

  The present invention relates to a container having a lid that can be opened and closed by a hinge.

  As one of the structures of containers such as cosmetic containers, there is one in which a lid is attached to a container body so as to be opened and closed by hinge engagement. Such a hinge engagement of a container generally uses a structure in which a shaft is rotatably inserted into a groove or hole (see Patent Documents 1 and 2). The lid can be smoothly opened and closed by such hinge engagement.

  However, in a container using a conventional hinge engagement, the lid cannot be stopped at a predetermined angle, and the lid must be completely opened when used. In particular, in the case of a cosmetic container having a mirror on the lid, there is a problem in that it is inconvenient if the lid cannot be stopped at a predetermined angle in order to make up while looking at the mirror.

  For this reason, some containers using hinge engagement use a free stop function that stops the lid at a predetermined angle (see Patent Documents 3 and 4). However, Patent Document 3 realizes a free stop function by a frictional force, and Cited Document 4 is a structure in which a knurling is formed on a shaft and a hole of the hinge engagement, which makes the structure of the hinge complicated. There is a problem with durability.

  In addition, since a container using a conventional hinge structure has a portion called a leg in the hinge portion, a certain amount of thickness is required in the hinge engaging portion, and the thickness of the container is reduced by the thickness of the hinge engaging portion. There was a problem that it was difficult to do. One method for solving such a thickness problem is that a thin container is realized by using a metal lid and making the hinge part compact like the container of Patent Document 5, Since such a structure is realized by using a metal, there is a problem that it is difficult to apply to a resin lid.

  Accordingly, an object of the present invention is to provide a container using hinge engagement that can reliably stop the lid at a predetermined angle with a simple structure in order to solve the above problems.

  The container of this invention is demonstrated in detail below in the form of the cosmetic container 1 using figures. FIG. 1 is a perspective view of the cosmetic container 1, and FIG. 7 is a side view of the cosmetic container 1.

  As shown in FIGS. 1 and 7, the cosmetic container 1 of the present invention includes a container body 2 and a lid 3 that is hingedly engaged with the container body 2. The container body 2 has a substantially rectangular planar shape, and a single accommodating portion 4 is formed therein as a space for accommodating cosmetics. The shape, the number, and the like of the accommodating portion 4 can be appropriately changed according to the item to be accommodated, and are not limited to the present embodiment.

  A first engaging portion 5 is provided at the rear end portion of the container body 2 in order to hinge-engage the lid 3. As shown in FIG. 4, the first engagement portion 5 has a groove 6 that is formed in an inverted U-shaped cross section and is open at the bottom, a part of which is curved above the upper surface of the container body 2. The portion protrudes, the curved surface portion is connected to the vertical portion of the back surface, and the bottom surface is formed in accordance with the inclination of the bottom surface of the container body 2. The first engaging portion 5 is formed at a horizontal central portion of the rear end portion of the container main body 2 with a width narrower than the width of the container main body 2, and the lid described later is provided on both sides thereof. A space in which the third second engaging portion 11 is accommodated is formed.

  Further, a convex portion 7 is formed on the inner surface of the groove 6 of the first engaging portion 5, a portion where the cross section of the groove 6 above the convex portion 7 is a semicircle, and the convex portion 7 A substantially cylindrical space extending in the horizontal direction with a part cut away is formed by the part surface.

  The lid 3 is formed in a size that covers the container body 2 and is disposed so as to sandwich the first engagement portion 5 of the container body 2 from the left and right at the rear end thereof as shown in FIG. A second engaging portion 11 that is hingedly engaged with the first engaging portion 5 is provided. The second engaging portion 11 includes two main body portions 12 and two shafts 13, and protrudes in the horizontal direction from the two main body portions 12 so that the cylindrical shafts 13 face each other. Further, the two main body portions 12 of the second engagement portion 11 are arranged at a predetermined interval so as to be positioned on both sides of the first engagement portion 5, and the shaft 13 is configured to be the first engagement portion. 5 is inserted into the groove 6. The shaft 13 is rotatably inserted in a substantially cylindrical space formed by a semicircular portion of the groove 6 above the convex portion 7 and a partial surface of the convex portion 7. The projection 7 is held so as not to fall off and to be rotatable.

  An inclined surface 15 is formed at the rear end of the lid 3 positioned between the two main body portions 12 of the second engaging portion 11 so as to incline upward from a surface in contact with the container main body 2 of the lid 3. Has been. The inclined surface 15 of the lid 3 is formed so as to be in contact with the surface of the first engaging portion 5, that is, in the tangential direction of the curved surface of the first engaging portion 5. When the lid 3 opens and closes, it rotates about the shaft 13. At this time, as shown in FIG. 8, the inclined surface 15 moves along the curved surface portion of the surface of the first engaging portion 5. The state in which the first engaging portion 5 is constantly in contact is maintained. Then, when the lid 3 is moved in the opening direction, the inclined surface 15 comes into contact with the vertical portion of the surface that becomes the back surface of the first engaging portion 5 as shown in FIG. The lid 3 is stopped in a state where the lid 3 is opened at a predetermined angle with respect to the container body 2. That is, the inclined surface 15 serves as a stopper when the lid 3 is opened.

  As shown in FIG. 9B, the lid 3 is stopped at a predetermined angle β with respect to the container body 2, and this angle is determined by the angle α of the inclined surface 15. As shown in FIG. 9, when the angle α of the inclined surface 15 is 130 °, the angle β between the lid 3 and the container body 2 is 140 °. This is because the sum of the angle α of the inclined surface 15 and the angle β of the lid 3 and the container body 2 is 270 °. Therefore, if the relationship between the angles α and β is expressed by an equation, α = 270 ° −β, and therefore the angle β between the lid 3 and the container body 2 when the lid 3 is opened is set to a desired angle. For this purpose, the angle α of the inclined surface 15 may be determined based on the above formula.

  The relationship between the angles α and β is established when the back surface of the first engagement portion 5 has a vertical surface, and the back surface of the first engagement portion 5 is inclined. In the case of a curved surface, it is necessary to consider the inclination angle or curvature. Further, when the inclined surface 15 is a vertical surface, the lid 3 opens to a horizontal state, and can be in the same state as a conventional container lid.

  When the lid 3 and the container body 2 are disassembled, the state shown in FIGS. In order to make the lid 3 hinge-engage with the container body 2 from this state, the shaft 13 of the second engaging portion 11 of the lid 3 is opened in the groove 6 of the first engaging portion 5 of the container body 2. Insert from the bottom up. Then, when the shaft 13 moves upward in the groove 6 and climbs over the convex portion 7 in the groove 6, the shaft 13 is formed in a substantially cylindrical space formed by a partial surface of the convex portion 7. to go into. At this time, the projection 13 prevents the shaft 13 from falling off, and the shaft 13 is rotatably held in the groove 6. In this way, the lid 3 is hingedly engaged with the container body 2. If the container main body 2 and the lid 3 are resin molded products, the first engaging portion 5 is deformed, so that the shaft 13 can easily get over the convex portion 7.

  In this embodiment, when the lid 3 is stopped in a state where it is opened at a predetermined angle, as shown in FIG. 7B, the bottom surface of the main body portion 12 of the second engagement portion 11 and the container main body The angle of the chamfered portion 10 of the corner is adjusted so that the chamfered portion 10 of the corner at the rear end of the two abuts. Thereby, it is also possible to have an auxiliary role of a stopper by the inclined surface 15.

  In order to fix the lid 3 to the container body 2 when the lid 3 is closed, a semi-cylindrical protrusion 8 is provided on the front surface of the container body 2, and a semi-cylindrical recess 14 is provided on the front surface of the lid 3. Combine. In addition, in order to increase the sealing degree when the container body 2 is closed with the lid 3, a rib 9 is provided on the upper surface of the container body 2 so as to surround the housing portion 4, and the container body 2 of the lid 3 is provided. A recess 16 corresponding to the rib 9 is provided on a surface in contact with the rib 9. The shape of the container body 2 and the lid 3, the fixing method when the lid 3 is closed, the shape and the number of the accommodating portions 4 of the container body 2, take into consideration what is accommodated in the container, the design, etc. Various forms are possible, and the present invention is not limited to this embodiment.

  As described above, the cosmetic container 1 according to the present invention uses the hinge engagement by the first engagement portion 5 and the second engagement portion 11 so that the lid 3 is formed with a simple hinge engagement structure. It is possible to stop the container main body 2 in a state where it is inclined and opened at a predetermined angle. Further, when the lid 3 is stopped in the opened state, the area where the lid 3 and the container body 2 come into contact with each other because the inclined surface 15 and the linear portion of the surface of the first engaging portion 5 come into contact with each other. Therefore, the stop state is firmly held with a simple structure.

  Furthermore, the cosmetic container 1 according to the present invention eliminates the need for a portion called a leg in the conventional hinge engagement by using the above-described hinge engagement, and reduces the thickness with a simple structure even if it is a resin container. Therefore, a thin and compact container can be realized as a container to be carried in a bag or the like.
